Hey Teachers! Here you have a new free resource to learn and practice some theory about the earth layers. This material has two parts: the atmosphere and the geosphere. Each part contains a worksheet with the information and the layers’ names, one activity to complete in color, one activity to complete in black and white and an easy and funny craft for kids.
The atmosphere is divided in five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The troposphere is the closest layer to the Earth. It is where meteorological phenomena happen and where human beings’ lives take place. The stratosphere is where the Ozone layer is, which is a thin part that absorbs almost all the harmful rays from the Sun. The mesosphere is the coldest layer. Here is where you can observe shooting stars. The thermosphere is where shooting stars and aurora boralis are formed. The exosphere is the last layer of the atmosphere before the outer space. Here is where artificial satellites are.
The geosphere is divided in three layers: the crust, the mantle and the core (divided in outer core and inner core). The crust is the outermost layer of the Earth and it is very thin. It moves slowly and it is where earthquakes take place. The mantle is the middle layer and it is very thick. In some places, rocks melt and go out through volcanoes’ craters. The core is the centre of the Earth and it is solid inside and molten outside. It contains heavy and thick materials, such as iron. Temperatures are very high.
The crafts are perfect to transform this theory in symbolic learning and make the children learn the information in a better way. To make the crafts you just need: glue, scissors and brads. We hope you can enjoy them!
